Xanten (amphitheatre)-A roman settlement, which was inhabited by 10,000 to 15,000 usually former legionaries, was given the rights of a Colonia in 110 by the Roman emperor Marcus Ulpius Traianus, who also renamed the city into Colonia Ulpia Traiana. The colonia became the second most important commercial post in the province of Germania Inferior, only beaten by Colonia Agrippinensis (today's Cologne).
